The formula is:
SI = P *( R/100) * T
Where symbols have their usual meanings.
(2/5) * P = P * (R/100) * 5
R = 8 percent per annum is the answer.

Let the sum be X
Given,
SI- 2*x/5
T- 5 y
Then,
R= SI ×100/P×T
= 2x/5*100/X*5
(x will cut 2x's x,;5 will cut 100 then it will be 20&then another 5will cut 20 then it will be 4,Hence 4*2 will be 8)
Hence ,rate will be 8%p.a
